Embodiment 1

[0067] see figure 1 as well as figure 2 , the third electrode 105 is the pixel electrode of the substrate to be printed 104, the orthographic projection of the third electrode 105 on the first electrode 102 is located in the first electrode 102, the third electrode and The first electrode 102 forms the printing electric field.

[0068] In this embodiment, the material of the first electrode 102 may be metal conductive material, ITO conductive material or other conductive material, which is not specifically limited here.

[0069] In this embodiment, the shower head 103 may protrude from the support 101 and extend toward the substrate to be printed 104 , and the first electrode 102 is located on the surface of the shower head 103 .

[0070] In this embodiment, the nozzle 103 can be embedded in the bracket 101, the nozzle of the nozzle 103 does not exceed the first surface of the bracket 101 near the substrate 104 to be printed, and the first electrode 102 is located on the f...

Embodiment 2

[0080] see image 3 as well as Figure 4 , this embodiment is the same or similar to Embodiment 1, the difference is:

[0081] The inkjet printing device 100 further includes a stage 106 located on a side of the substrate to be printed 104 away from the support 101 .

[0082] Wherein, the second electrode 107 is located on the stage 106, the orthographic projection of the first electrode 102 on the second electrode 107 is located in the second electrode 107, and the second electrode 107 and the The first electrode 102 forms the printing electric field.

[0083] In this embodiment, the material of the second electrode 107 may be metal conductive material, or ITO conductive material or other conductive material, which is not specifically limited here.

[0084] In this embodiment, through the second electrode 107 arranged on the stage 106, the first electrode 102 and the second electrode 107 form the printing electric field, which is beneficial to avoid when the shower head 10...

Abstract

The invention provides an ink-jet printing device and an ink-jet printing method. The ink-jet printing device comprises a spray head, a support for fixing the spray head and a first electrode locatedon the support or the spray head; the spray head and the first electrode are located on the side, close to a to-be-printed substrate, of the support; and the first electrode and a second electrode located on the ink-jet printing device, or a third electrode located on the to-be-printed substrate form a printing electric field, and the printing electric field is used for enabling solute in ink to be evenly distributed on the to-be-printed substrate. According to the ink-jet printing device and the ink-jet printing method, the first electrode and the second electrode, or the first electrode andthe third electrode form the printing electric field, so that solute in ink is uniformly distributed on the to-be-printed substrate under the action of the electric field, the coffee ring effect is avoided, and the product quality is improved.

Description

technical field [0001] The present application relates to the display field, in particular to an inkjet printing device and an inkjet printing method. Background technique [0002] With the rapid development of display products, people continue to develop the manufacturing process of display products. As a vacuum-free, direct patterning, low-temperature and low-cost patterning technology, inkjet printing has attracted widespread attention. [0003] After the existing inkjet printing device ejects the ink, due to the coffee ring effect, the solute in the ink deposits unevenly on the substrate to be printed, which affects the quality of the display product using the substrate to be printed. [0004] Therefore, there is an urgent need for a new inkjet printing device and inkjet printing method to solve the above technical problems. Contents of the invention [0005] The present application provides an inkjet printing device and an inkjet printing method, which are used to so...
